Inventor: TAZAWA KAZUYUKI
IPC: G01R31/36
Filed: 1989-02-16
Abstract: PURPOSE:To enable the prevention of a misjudgment caused by a drop in a source voltage by comparing with a preset reference current value a circuit current value calculated from an output of a current detection sensor when the source voltage of an electric circuit exceeds a specified voltage to accomplish a judgment of abnormality in the electric circuit accurately with simple construction. CONSTITUTION:A current detection sensor 23 and a circuit condition judging means 35 are arranged. Then, current supplied to an electric circuit is detected by the sensor 23 and when a source voltage of the electric circuit exceeds a specified value, a circuit current value based on the sensor 23 is calculated by a judging means 35 to be compared with a reference current value preset. Then, it is judged whether the electric circuit is normal or not. In other words, as the source voltage of the electric circuit becomes smaller than the specified value, judgment of abnormality of the electric circuit is stopped.

Filed: 1993-02-02
Abstract: PURPOSE:To provide a recording and reproducing device which corrects the both of the time base error on a reproducing side and the time base error due to the recording servo characteristic on a recording side and prevents the occurrence of the time base error due to the repeating of dubbing. CONSTITUTION:A variable delay circuit 13 is inserted between a reproducing amplifier 4, an FM demodulation circuit 5 and a recording amplifier 8. A reference synchronizing signal generation circuit 15 prepares a horizontal synchronizing signal to be a reference based on the vertical synchronizing signal reproduced in a synchronizing separation circuit 7.

Title: Cathode-ray tube
Inventor: TOKITA KIYOSHI
IPC: H01J29/24
Filed: 1983-03-09
Abstract: PURPOSE:To obtain a cathode-ray tube having a glass panel excellent in mechanical strength by providing the specific relations in the thickness of glass among the vertical axis direction, horizontal axis direction and diagonal axis direction near the substantially rectangular frame of the glass panel face part. CONSTITUTION:The thickness tv, tH and tD near the rectangular frame in the respective directions of the face part are constituted so as to have the relations tv>=tH and tD>=tH. In order to constitute the thickness near the rectangular frame in the respective axial directions of the face part in this way, it is effective to make the outer surface radiuses of curvature Rv, RH and RD as well as the inner surface radiuses of curvature R'v, R'H and R'D in the respective axial directions of the face part, X in such relations as Rv<=RH<=RD, and R'v<=R' and also R'D<= R'H. Or, it is also effective to make Rv>=RH further RD>=RH and R'v>=R'H>= R'D. Thereby, since the thickness of the upper end in the screen vertical axils direction, in which mechanical expansion stress due to the atmospheric pressure becomes maximum, is formed sufficiently large, sharply improved mechanical strength can be obtained.

Title: Hearing aid
Inventor: MEGATA TSUYOSHI
IPC: H04R25/04
Filed: 1990-02-19
Abstract: PURPOSE:To prevent howling caused at demounting with simple configuration by connecting an input terminal of a circuit whose gain is increased at application of power and reaches a constant gain after lapse of a prescribed time to an output terminal of a sound receiver and connecting the input terminal of a sounder. CONSTITUTION:An output signal voltage of a gain control signal generating circuit 370 increases according to lapse of time after a power switch 350 is connected and the output voltage reaches a constant voltage at a lapse of a time t1. An output signal terminal of the circuit 370 connects to a gain control signal input terminal of a gain control amplifier 330. Thus, the gain of the amplifier 330 increases gradually and reaches a constant value at a lapse of the time t1. The insertion gain of a hearing aid 340 is varied with a change in the gain and the gain reaches a gain required for the user after the time t1. The time t1 is set to be longer than the time required for mounting the hearing aid. Thus, since the insertion gain is low while the hearing aid is mounted, no howling is caused.

Filed: 1995-02-02
Abstract: PURPOSE: To enhance functions by raising the upper ends of expansion links whose lower ends are connected to a vertical frame, raising a number of slats one by one whose ends are supported on the expansion links, and closing an opening by inclination of the slats. CONSTITUTION: When an opening is open, lines 27, 30 of links are folded and slats 4 are closely stacked below the opening. When the opening is closed, an output rotating shaft 79 is rotated by operation of an electric motor 78, and a moving stand 75 moves up a guide course via gears, pulleys and a belt 69, etc. Then the lines 27, 30 of links are also extended from their upper ends and the slats 4 are raised one by one in a direction for closing the opening. In a predetermined position a tilt arm 91 and cam surfaces 86, 97 work in collaboration for the slats 4 to be rotated counterclockwise and held in the vertical direction so as to fully close the blind. Thus a feeling of openness can be prevented from degrading due to the slats stacked above the opening, and only the lower side of the opening can be closed.

CONSTITUTION:First of all, a plug main body 11 is formed by injection molding. The plug main body 11 is inserted and loaded on a clamping platen 21 or movable platen 22 of an injection mold. Then, a heat fused thermoplastic elastomer enters into a cavity 26 from a nozzle of the injection molding machine. As a result, the macromolecule of the plug main body 11 and the thermoplastic elastomer are mixed and bonded to form a heat fused surface 13. On the lower surface outer periphery of the plug main body 11, a gasket 12, which is ring- shaped and has a rectangular cross section, is bonded integrally by injection molding. The material of the gasket 12 is thermoplastic elastomer. Between the lower surface of the plug main body 11 and the gasket 12, there is the heat fused surface 13. At the upper part of the inner surface of the plug main body 11, a half circular packing 20 has been fusion-fixed. Since these can be integrally injection molded, the manufacturing processes can be reduced.
